VENTILATOR FOR CLOSED-VEHICLE BODIES.

Specification of Letters Patent.

Patented Slept. 21, 1915.

To all 'whom it may concern.'

' Be it known that I, MATTHEW R. HULL,

la citizen of the United States, residing at Connersville, in the county of Fayette and State of Indiana, have invented certain new and useful Improvements in Ventilators for Closed-Vehicle Bodies, of which the following is a specification.

This invention-relates to the ventilation of closed vehicles through side windows, and the object is to provide means for opening the windows a regulated distance and for holding them open or closed without rattling. p

A further object is to provide means for the ready removal of the windows when the maximum opening for ventilation is desired.

Referring to the accompanying drawingsy wherein like characters of reference indicate like parts, Figure 1 is an elevation of a window viewed from the inside of the vehicle body embodying my inventiom'andFig. 2 is a vertical section on the line 2 2 of Fig. 1..

The window frame 3 is mounted inany suitable manner in the vehicle body 4:, and fastened to the top of the frame is a metal; strap 5, the end of which projects inwardly from the frame for several inches, or far enough to aiord room for the attachment to it of a spring sash stop 6. The latter is of strap metal, spring tempered, of substantially U-shape, one stem of which contacts the under side of the projecting strap 5, to which it is drawn by a set screw 7. is seated in the strap 5 and depends between the frame 3 and the screw. This pin enters a suitable hole in the stem of the spring Stop 6, holding the latter in alinement with the strap 5 under normal conditions of use, but also permitting the member 6 to be turned at right angles to the position shown indotted lines in Fig. 1. rlhe bend connecting the two stems of the U-shaped stop 6 is more than semi-circular to form a shoulder 10 where thei lower stem begins, and the inner end of the lower stem is bent inwardly at 11.

A window sash 12 having a glass 13 rests in the frame 3 on a sill 111 in the customary rabbet, and the sash swings on its lower end to the position shown by dotted lines in Fig. 2,-the removal of the lower end being restrained by a strip 15' in the bottom rabbet of the frame 3.

Fastened to the top of the sash 12 is a A pin 8- strap-metal pull 15 which projects inwardly of 'the vehicle in the form of a.v hook, as shown. yIt projects upwardly of the sash and forms a bearing for the spring stop 6, at all times while the sash is in its frame.

In the operation of my device, the window 4swung about its lower end to the position shown by the dotted lines in Fig. 2, by pulling on the member r15. This opening movement is limited by the contact of the pull 15 against the shoulder 10 of stop 6, and the resiliency of the latter will insure pressure and friction against the pull 15 to hold the window sash open without rattling.

By loosening the set screw 7 the upper stem of stop 6 may be disengaged from pin 8 which will permit the stop to be turned to the position shown by dotted lines in Fig. 1, the lower stem thus relieved from the pull will swing down which leaves the pull 15 unhampered by the stop. The topof the .is held in its closed position against rattling by the pressure of the stop 6 against the pull sash may then be swung out to clear the top ing the full opening available for the circulation of air.

Having thus fully described my invention what l claim as new and wish to secure by Letters Patent of the United States, is

1. ln a ventilator, a frame, a sash mounted therein to swing on its lower end, and a spring stop secured to the trame at the upper end of the sash., said stop limiting the opening of the sash and pressing against it to eliminate looseness and rattle in closed and open positions.

2. ln a ventilator, a frame, a sash mounted in the 'frame to swing on its lower end, a spring stop secured to the frame at the upper end of the sash said stop limiting the opening of the sash and pressing against it to eliminate-looseness and rattle in closed and open positions and means 'for adjusting the stop out of the way of the sash for the `bearing elastically against said sash pull and means on the stop tolimit the swing of the sash while maintaining said'elastic bearlng.

4. In a ventilator, a frame, a sash mounted in the frame to swing on its lower end and having a. projecting pull at its upper end, a U-shaped spring stop secured by one stem and having its other stembea'ring againstsaid sash pull, means on the stop to limit the swing,` of the sash and means for adjusting thlsl'stop out of interference with the sash pu In witness whereof, I have hereunto set my hand and seal at Connersville, Indiana,

this 14th day of June, A. D. one thousand .'-3

nine hundred and fifteen.
